' MOTOR VEHICLE AND THE LIKE.; I

. Application filed July 30. 1921. Serial No. 488,657.

To all whom t may concern.' Y

Be it known that l, SYLvaIN Coumnn, a subject of the Kin@ of Belgium, residing at Schaerbeek, near russels, Belgium, have invented certainnew and useful Improve ments in or Relating to Motor Vehicles and the like, of which thefollowiug is a specification. i

This invention relates to motor vehicles and the like'and refers more .particularly to the front trucks of such vehicles.

The invention has for its main object to provide improved means of supporting the front truck and the motor mechanism.

The arrangement forming the subject of the present invention is distinguished from the known devices by carrying a diderential connected by means of two transverse shafts with universal joints to the wheels of the vehicle directly or throughthe lintermediary of toothed gearings.

The application of this mode of transmission to motor vehicles provided with front trucks enables'the motor, the change speed gear and the differential to .be grouped in acompact unit which may be secured under the front truck and near the front axle; thereby leaving free the space beneath the axle.

This disposition renders Athe front truck completely removable and applicable toall kinds of vehicles.

` The disposition of the present inventionv can vbe applied to all kinds of motors.`

The invention is illustrated by `way of example in the accompanying drawings wherein Y Fig. 1 is a front View (the radiator is removed). f

Fig. 2 is a side view partly in section of the motor mechanism and front truck.

The front truck illustrated in Figs. 1 and 2 comprises an upper xed part 1 supportin f the steering column 2, pedals and contro levers of the motor and its adjuncts. This part 1 is xed to the'frame 3 of the vehicleand is supported on a lower part d by means of rollers 54 and carries a hollow sleeve 6 on which the two parts 1 and 11 are centrally mounted. The controlling trans-v mission of the various parts passesthrough this hollow sleeve. 'c

The lower part 4 rests upon an axle through the intermediary of plate springs 8 fixed at or near their central portions 9 to the axle and connected at their two extremities with the outer arms of a pair of bellcrank levers 10 pivoted on the said lower part l. The free ends of the inner arms of the two levers 10 are united by means of a rod 11.

The motor mechanism comprising a motor 12, change speed gear 13 and differential 18, and the radiator 111' and .Oasoline and oil tanks, are supported on an under-frame 15 suspended from the lower part d. The main shaft 16 of the motor is parallel with the axle and transmits its motion by toothed gearing to the primary shaft 17 of the change speed gear'. c

@n each side of the differential 18 is a transverse shaft 19 each of which is provided at each end thereof with a universal joint 20. The joints on the opposite side to the differential unite the shafts 19 with the axles` 21 of wheels 22 which are loosely mounted on said axles interdependent with the axle 7. y

This suspension permits the transverse shafts 19 to be always maintained in the same lane. y

lt will be seen that the device according to the present invention can be applied to all kinds of motors with horizontal, vertical or inclined cylinders. The motor shaft can be parallel or perpendicular to the axle. The motor, differential and change speed gear can be supported on one frame or on separate frames. In` the example given internal combustion engines have been referred to7 but it is evident that the device forming the object of the inventionV can be also applied to `a steam motor with an instantaneous vaporization boiler.

The axle may be of any `convenient form depending upon the mode of suspension adopted for the mechanism.

The driving gear may be cylindrical or conical and be placed between the shafts 19 and the differential or at the two ends of the shafts 19. c

1 claimas my invention `ln a motor vehicle front truck, a fixed member secured to the frame; a revoluble member associated with the fixed member; an axle; support-ing springs connecting the ends of the axle and the revoluble member; a pair of steerable wheels having their axles movably mounted in the ends of the first named axle; a sub-frame secured to said revoluble member; a motor nnit mounted dineotions With the latter ai? their inner ends,
